Researchers in California and Florida lead by Andrew I. Caster, MD brings good news for patients with corneal thickness of 500 µm or less who are due for LASIK surgery.
In a study published in the October issue of Journal of Refractive Surgery, the researchers, after reviewing outcomes for 109 eyes of 69 LASIK patients who had a preoperative central corneal thickness between 452 µm and 500 µm, concluded that LASIK patients with a preoperative central corneal thickness of 500 µm or less do not have an increased risk of post-operative Keratectasia.
1. The researchers observed no clinical signs of Keratectasia in any eye at any postoperative follow-up point.
2. They also found no correlation between preoperative pachymetry and refractive change between 1 month and 12 months follow-up.
3. Additionally they observed no statistically significant change in either mean spherical equivalent or manifest cylinder between 1 month and 12 months. Source: OSNSuperSite
Note: Keratectasia is abnormal bulging of the cornea of the eye.
